CrossLoop is a free secure screen sharing utility designed for people of alltechnical skill levels. CrossLoop extends the boundaries of VNC's traditionalscreen sharing by enabling non-technical users to get connected from anywhere onthe Internet in seconds without changing any firewall or router settings. Itonly takes a few minutes to setup and no signup is required.

Security is built into all aspects of CrossLoop. Session data is encrypted atthe end-points before being sent using a 128-bit encryption algorithm using arandomly generated 12-digit access code. Explicit permission is required beforeany screen images are sent to a remote computer. CrossLoop is a secure tool toremotely assist any PC on the planet.

CrossLoop's underlying technology was created to simplify the process ofsecurely working with others located in different physical locations acrossdiverse network environments. CrossLoop enables you to see the screen andcontrol the mouse and keyboard on a remote computer using VNC. It is as if youare working side by side at the same PC. CrossLoop is a powerful productivitytool that enables you to quickly collaborate in with anyone in the world.

CrossLoop is powered by the proprietary CrossLoop VIP Tunnel, a securepeer-to-peer data transmission system. CrossLoop encrypts all files and messagesexchanged on our network to ensure user privacy. Only you and your invitedfriends or family can view or share control of your computer. A CrossLoopsession can only begin on your computer by explicitly inviting them to begin asession. All data sent over the CrossLoop network is encrypted at the endpointsusing a 128-bit Blowfish encryption.

The Windows version of CrossLoop uses the TightVNC software plug-in forscreen sharing. We have included a binary distribution of the TightVNC programin the installation software of the Windows version of CrossLoop to save youthe trouble of separately downloading and installing TightVNC.
